Yantian Water Body Remote Sensing Classification

Saltworks, lying in up of tide flat, is the region acted integratedly by the ocean and the land. It is very significant to investigate and evaluate the saltworks resource in detail. Salt field production is a ecologic, sustainable industry, which is low devoted but high outputed and necessary for chemistry industry, so it is very essential to strengthen the macro-supervise research of saltworks and increase the rationality and validity of the layout and administration of saltworks. This paper discusses how to supervise the salt field water by using remote sensing technology, the main content in the dissertation include:(1) The background and significant of the study.(2) In terms of measured data, we analyse the spectrum characteristic of the vary kinds of water, and summarize that the content of NaCl has little influence on the spectrum absorption coefficient in the pure solution of saltworks.(3) We introduce the course of applying the relative scatter model, and test the result of the atmospheric scattering correction.(4) We compare the virtue and the flaw of the data fusion techniques, and accurately separate the research region by principal component analysis data fusion technique.(5) Based on the spectrum characteristic of the vary kinds of water, we expound the method to extraction them, improve the method of proportion estimation, put forward the best opportunity for extractioning the water of salt field.(6) Summarize the methods to estimating the yield of crop, and discuss the methods to estimating the yield of salt field by remote sensing, combining the process of salt field production.
